Transcranial Direct Current Stimulation (tDCS) is a form of non-invase neurostimulation that delivers a constant low level current to the brain through the use of electrodes placed on the scalp. This neuromodulation technique uses a steady current between 1 - 2 mA delivered through electrodes to targeted regions of the brain to modulate brain function. Using different electrode configurations, tDCS can be used to either excite or inhibit neuronal activity in the targeted region.
Headquartered in New York City, Caputron is the leading worldwide distributor of home, clinical and research neurostimulation technology, such as tDCS, TMS, CES and EEG. By partnering with world-class device manufacturers, we supply a range of excellent neurostimulation devices and accessories, such as Transcranial Magnetic Stimulation (TMS), Cranial Electrotherapy Stimulation (CES) and Transcranial Direct Current Stimulation (tDCS).
Small, handheld, easy to use tDCS brain stimulator with ramp-up and ramp-down functionality and a 1 mA to 4 mA intensity range and duration range of 5 to 35 minutes. Includes 0.75Hz sotDCS mode – slow oscillating transcranial Direct Current Stimulation.
Focus Go Flow is a hand-held battery-powered easy to use tDCS brain stimulator. The device utilizes a microprocessor controlled circuit to provide an accurately regulated current. Unlike other commercially available 9 volt devices, the Go Flow features a voltage step up circuit that provides a max voltage of 25V. This ensures the ability to provide up to 4 mA of current with any traditional tDCS montage. The Go Flow also features a built in timer. Simply set the session length you want and let Go Flow do the rest. The microcontroller will provide a smooth ramp up and ramp down of current, a feature that is overlooked by other devices but extremely important for tDCS. The backlit duration and intensity indicators provide for a quick and easy method to read your specified settings.
Go Flow is an extremely easy to use portable tDCS device.
When turned on, the device will default to your last used intensity and duration settings. Slide the knob up and down during the stimulation to adjust the intensity setting to a comfortable level. Once started, the device LED indicator will alternate every 5 seconds between intensity and duration to let you know how much time is remaining in your session. When the set time is reached and the session is over, the Go Flow will automatically ramp down the current. If for any reason you need to stop stimulation, simply click in the slider knob and the Go Flow will safely ramp down the intensity.
How to enter 0.75Hz sotDCS modeTo start Go Flow in sotDCS mode you must press the red button twice - a short press, followed by a longer press. When turned on in sotDCS mode you will see the rainbow flash confirmation in red instead of the usual green. This montage uses the dual X/Y cable. This information can be found on page 12 of the Go Flow 4 manual.
How to check Go Flow battery levelYou can check the approximate charge of a battery by pressing and holding the rocker button. The green lights will show a value between full (all lights) and 15% (one light) with 15% intervals for each lit light. If the lights do not illuminate when Go Flow is connected to a battery, the battery has no charge.
Is it possible to change the current during an active tDCS sessionYes, use the rocker switch to increase or decrease the current. During active sessions it is possible to use increments of .25 mA. Each increase or decrease will be applied at a rate of 0.25 mA per second. The gauge will switch to orange lights when changes to the active current are being made. You can press the rocker button at any time to STOP the stimulation at which point the current will ramp back down to 0.
What do the flashing lights meanFlashing green and orange - No electrodes connected. Connect electrodes and start again. Flashing orange - Resistance in electrodes too high and cannot reach 0.5mA. Check the electrodes setup and start again.No lights = dead battery. Start again with a new, fully charged 9v battery.

I bought the Go Flo 4, and I really like the device so far. Its tiny, but powerful. NOTE: In order to turn the device on, you have to press and hold the red button for 2 seconds in NEUTRAL position (not pressed up or down). This isn't very clear from the instructions, but the folks at Caputron were able to help me out. They are super nice and VERY fast in responding to emails. Truly Top Knotch customer service...I'll definitely be purchasing from them again!
good quality device with many options
Very happy with this device. Small and portable, I can take it with me when needed for when I can't make my TMS session. I have found this very beneficial and easy to use. Great support from Caputron with this device and happy to have found them.
